mlr3mbo 0.3.3

• compatibility: bbotk 1.7.0

mlr3mbo 0.3.2

• compatibility: mlr3learners 0.13.0

mlr3mbo 0.3.1

• chore: maintainer change.
• chore: work with new mlr3pipelines version 0.9.0 (fix for tests only).
• test: expect_rush_reset changes related to rush developments.
• fix: allow InputTrafoUnitcube to work in mixed spaces.

mlr3mbo 0.3.0

• fix: logger changes related to bbotk.
• fix: assure that candidates after acquisition function optimization are always within bounds.
• perf: minor changes to speed up predictions with SurrogateLearner and SurrogateLearnerCollection.
• feat: added supported for input and output transformations (see InputTrafo, OutputTrafo and the related classes).
• refactor: dropped functionality to assert insample performance of the surrogate model completely.

mlr3mbo 0.2.9

• chore: silence rush logger and fixed some partial matches, depend on mlr3 >= 0.22.1.
• test: fix test_AcqFunctionMulti, robustify helper and loading.
• test: fix test_ResultAssignerArchive and test_ResultAssignerSurrogate due to upcoming changes of internal tuned values in mlr3tuning 1.3.1.

mlr3mbo 0.2.8

• docs: gracefully exit examples of OptimizerAsyncMbo, OptimizerADBO, TunerAsyncMbo, and TunerADBO if Redis is not available.
• test: skip tests involving asynchronous logic if Redis is not available

mlr3mbo 0.2.7

• refactor: refactored SurrogateLearner and SurrogateLearnerCollection to allow updating on an asynchronous Archive.
• feat: added experimental OptimizerAsyncMbo, OptimizerADBO, TunerAsyncMbo, and TunerADBO that allow for asynchronous optimization.
• feat: added AcqFunctionStochasticCB and AcqFunctionStochasticEI that are useful for asynchronous optimization.
• doc: minor changes to highlight differences between batch and asynchronous objects related to asynchronous support.
• refactor: AcqFunctions and AcqOptimizer gained a reset() method.

mlr3mbo 0.2.6

• refactor: Extract internal tuned values in instance.

mlr3mbo 0.2.5

• docs: Move vignette to mlr3book.
• feat: Add AcqFunctionMulti that can wrap multiple acquisition functions resulting in a multi-objective acquisition function problem.
• feat: Support callbacks in AcqOptimizer.
• feat: Allow AcqFunctionEI to be adjusted by epsilon to strengthen exploration.

mlr3mbo 0.2.4

• fix: Improve runtime of AcqOptimizer by setting check_values = FALSE.
